- the image-wise heating of the recording material with the thermal printing heads may proceed through a contacting but removable resin sheet or web wherefrom during the heating no transfer of recording material can take place.
- Activation of the heating elements can be power-modulated or pulse-length modulated at constant power.
- EP-A 654 355 discloses a method for making an image by image-wise heating by means of a thermal head having energizable heating elements, wherein the activation of the heating elements is executed duty cycled pulsewise.

- the substantially light-insensitive organic silver salt of the thermosensitive element of the thermographic recording material of the present invention comprises silver behenate (AgB)
- the results shown in table 2 were obtained as a function of temperature.
- the formation of Ag° is clearly promoted at temperatures between 100 and 150°C by the presence of glutaric acid (I-1) rather than adipic acid (D02), representing prior art materials, and the addition of glutaric acid to silver behenate with R02 results in a much more rapid disappearance of phase I silver behenate.
- the substantially light-insensitive organic silver salt of the thermosensitive element of the thermographic recording material of the present invention comprises silver behenate
- silver behenate is present subsequent to thermal development partly as an amorphous phase, as phase III and depending upon the composition also as phase I.
- Certain compounds including certain stabilizers according to formula I, e.g. glutaric acid, and the toning agent T02 (7-(ethylcarbonato)-benzo[e][1,3]oxazine-2,4-dione) surprisingly have been found to stabilize phase III silver behenate at room temperature.
- thermographic recording materials of the present invention in which the substantially light-insensitive organic silver salt comprises silver behenate a reddish change in the image tone from a blue-black tone to a more brownish tone may take place subsequent to thermal development, particularly if the thermal development time is reduced below 12ms.
- X-ray diffraction measurements in real time have shown that this change in image tone subsequent to thermal development is accompanied by changes in the phase structure of the silver behenate.
- amorphous silver behenate is converted into phase I and phase III silver behenate in the first 15 minutes after thermal development.
- thermographic recording material of the present invention considerably reduces this effect and phase III silver behenate is principally observed with very little phase I silver behenate.
- the silver behenate is partly present as phase II, with an X-ray diffraction spectrum upon irradiation with a copper K ⁇ 1 X-ray source with Bragg angles 2 ⁇ of 5.34-5.67°, 6.24°,7.77°, 8.30-8.45°, 9.37°, 10.92°,and/or phase III silver behenate, with an X-ray diffraction spectrum upon irradiation with a copper K ⁇ 1 X-ray source with Bragg angles 2 ⁇ of 4.76-4.81°, 5.9-6.18°, 6.76-7.02°, 8.29°, 9.06°, which is stable at room temperature.
- Image-wise heating of the recording material can also be carried out using an electrically resistive ribbon incorporated into the material.
- Image- or pattern-wise heating of the recording material may also proceed by means of pixel-wise modulated ultra-sound.

During this line time the print head received constant power. The printing power was 65.8mW and the thermal head resistors were time-modulated to produce different image densities.
- the image tone of fresh prints made with the substantially light-insensitive thermographic recording materials of COMPARATIVE EXAMPLES 1 and 2 and INVENTION EXAMPLE 1 was assessed on the basis of the L*, a* and b* CIELAB-values as described above.
- the b* CIELAB-values of fresh prints of the substantially light-insensitive thermographic recording materials of COMPARATIVE EXAMPLES 1 and 2 and INVENTION EXAMPLE 1 at an optical density, D, of 1.0 measured at least 24 hours after printing (i.e. after stabilization of the image tone) are also given in Table 4. Comparative example nr.
- thermographic recording material of INVENTION EXAMPLE 1 is clearly bluer than that of the thermographic recording materials of COMPARATIVE EXAMPLES 1 and 2, without loss in image density.
- Colour neutrality on the basis of CIELAB-values corresponds to a b* value of zero, with a negative b*-value indicating an increasingly bluer image-tone as b* becomes more negative and a positive b*-value indicating a yellowish image-tone becoming more yellow as b* becomes more positive.
- the image tone of elements of the image with a density of 1.0 have a stronger effect than the image tone of elements with lower or higher optical. It is clear from the results of table 4 that the print produced with the thermographic recording material of INVENTION EXAMPLE 1 surprisingly has a substantially bluer tone, i.e. having a b*-value ⁇ 0, than the prints produced with the thermographic recording materials of COMPARATIVE EXAMPLES 1 and 2, which have b*-values > 0. This demonstrates the surprising improvement in image tone of the present invention over the invention of EP-A 687 572.
- thermographic materials according to EP-A 687 572 compared with that of thermographic materials of present invention
- thermographic recording materials of COMPARATIVE EXAMPLES 3 to 8 according to the invention of EP-A 687 572 and INVENTION EXAMPLES 2 to 7 were produced by doctor blade-coating a subbed 175 ⁇ m thick non-pigmented polyethylene terephthalate support with a composition containing 2-butanone as solvent/dispersing medium so as to obtain thereon, after drying, the thermosensitive elements of COMPARATIVE EXAMPLES 3 to 8 and INVENTION EXAMPLES 2 to 7 with the compositions given in Table 5: Comparative example nr.
- Colour neutrality on the basis of CIELAB-values corresponds to a b* value of zero, with a negative b*-value indicating an increasingly bluer image-tone as b* becomes more negative and a positive b*-value indicating a yellowish image-tone becoming more yellow as b* becomes more positive.
- thermographic recording materials of INVENTION EXAMPLES 8 to 11 and COMPARATIVE EXAMPLE 9 were produced by doctor blade-coating a subbed 175 ⁇ m thick non-pigmented polyethylene terephthalate support with a composition containing 2-butanone as solvent/dispersing medium so as to obtain thereon, after drying, the thermosensitive elements of INVENTION EXAMPLES 8 to 11 and COMPARATIVE EXAMPLE 9 with the compositions given in Table 7. Comparative example nr.
- Colour neutrality on the basis of CIELAB-values corresponds to a b* value of zero, with a negative b*-value indicating an increasingly bluer image-tone as b* becomes more negative and a positive b*-value indicating a yellowish image-tone becoming more yellow as b* becomes more positive.
- the b* value of the print produced with the thermographic recording material of INVENTION EXAMPLE 13 having the same composition as the thermographic recording material of INVENTION EXAMPLE 12 merely shows the effect of using the MEDICAL IMAGING SUPPORT 4, blue-pigmented polyethylene terephthalate support, rather than a non-pigmented polyethylene terephthalate support.
- the drifts of the thermographic recording materials of INVENTION EXAMPLES 14, 15, 16 and 17 are acceptable for line times of 11.8 and 7.Oms, but it is desirable to reduce the line time to 4.5ms so that the throughput can be optimized.
- thermographic recording material of INVENTION EXAMPLE 15 containing glutaric acid as the stabilizer compound according to formula I together with the reducing agent R03 (3,4-dihydroxybenzonitrile).
- the drifts of the thermographic recording materials of INVENTION EXAMPLES 14, 15, 16 and 17 are acceptable for line times of 11.8 and 7.Oms, but it is desirable to reduce the line time to 4.5ms so that the throughput can be optimized.
- the shifts in a*(24h) values upon line time reduction from 1.8 to 7.0 ms are also acceptable for all the thermographic recording materials of INVENTION EXAMPLES 14, 15, 16 and 17, but these materials exhibit significant differences upon further line time reduction to 4.5 ms with shifts varying between +3.9 for the thermographic recording material of INVENTION EXAMPLE 15 and +9.6 for the thermographic recording material of INVENTION EXAMPLE 14.
- thermographic recording materials of INVENTION EXAMPLES 14, 15, 16 and 17 are all suitable for use with printers with line times of 11.8 and 7.0ms as regards a* and b* drift, but only the thermographic recording material of INVENTION EXAMPLE 15 is suitable for use with a printer with a line time of 4.5ms. If the shift in absolute image tone with decreasing line time is taken into account, the shift in b* values after 24 hours is fairly small and either negative or only slightly positive and hence is acceptable.
- thermographic recording material of INVENTION EXAMPLE 15 has an acceptable shift in b* and a* values after 24h.
